JM JM20336
The JM20336 is a bridge controller, which translates the communication protocol between SATA II 3.0G and Hi-Speed USB commands. The integrated 15MIPS 8051, dual-port SATA II 3.0G and Hi-Speed USB technology enable users to perform Hi-Speed USB to SATA II 3.0G, and SATA II 3.0G to SATA II 3.0G applications in a signal chip. The SATA controller could be configured as host or device.DESCRIPTION
In this chip, the Hi-Speed USB controller supports the USB Mass Storage Class Bulk-Only Transport Specification, and support dual LUN applications. The dual-port SATA II 3.0G controllers further support the SATA to SATA communication.FEATURES
